Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508540, here are decompositions:

23 + 508517 = 508540
41 + 508499 = 508540
89 + 508451 = 508540
101 + 508439 = 508540
107 + 508433 = 508540
167 + 508373 = 508540
173 + 508367 = 508540
191 + 508349 = 508540

Showing the first eight; more decompositions exist.
